Abstract:
The influence of three-body interactions on thermodynamic response functions in the extended critical region is investigated by using molecular simulations. Results obtained with a high-level ab initio two- and three-body potential for krypton are compared to those from the Lennard-Jones potential and a reference equation of state. While the former model shows excellent agreement with the equation of state, the Lennard-Jones potential exhibits significant deviations that cannot be corrected by parameter adjustment, emphasizing the importance of many-body effects for quantitative predictions.

¹H NMR: Long-Range Coupling
In alkenes, spin information is communicated via σ–π overlap, as seen in allylic (four-bond) and homoallylic (five-bond) couplings. These coupling interactions are stronger when the σ bond is parallel to the alkene π orbitals.
Spin–Spin Coupling: Three-Bond Coupling (Vicinal Coupling)
The extent of coupling depends on the C‑C bond length, the two H‑C‑C angles, any electron-withdrawing substituents, and the dihedral angle between the involved orbitals. The...
